As he heard her story he felt guilty, where he's from most things are build by slaves. But at the same moment he didn't felt sorry, he heard worse stories and due to his cold character he probably just didn't care about ones past. He thought about replying to what she told him but that probably wouldn't have helped. Therefore he watched her  warming up at the fire. It reminded him, they are out of wood and it's impossible to survive outside the cave even for a short period of time. Especially because they both are tired. The next thing to happen catched him by surprise, this woman he just met a few hours ago walked towards him sat down and rested against his chest. He was fairly confused but rtied his best to not move, he actually lacked the energy to do anything at all. So instead he just started petting her head a bit. He noticed that the giant spider has moved closer for some reason, clearly in an alerted status towards him. Therefore he stopped the petting and just laid his head against the cold cave wall and soon fell asleep as well.
